1. What Exactly Is Ringworm In Cats?
Ringworm in cats is not caused by worms but rather by a fungal infection of the skin, hair, and nails. Ringworm, technically known as dermatophytosis, is caused by dermatophytes, fungi that thrive on keratin, a protein found in skin, hair, and nails.
1.1. What Causes Ringworm in Cats?
Ringworm in cats is primarily caused by dermatophytes, particularly Microsporum canis, which accounts for about 98% of ringworm infections in felines. These fungi thrive in keratin, a protein found in skin, hair, and nails. Transmission occurs through direct contact with infected animals or contaminated objects like bedding, grooming tools, and surfaces. The spores of dermatophytes are highly resilient and can survive in the environment for up to 18 months, making environmental contamination a significant factor in the spread of the infection. Factors such as a cat’s age, health, and hygiene also influence their susceptibility to ringworm.
1.2. How Common Is Ringworm in Cats?
Ringworm is a fairly common skin infection in cats, especially among kittens and cats with weakened immune systems. According to the American Animal Hospital Association (AAHA), ringworm is one of the most common dermatological conditions seen in cats. Shelters and catteries, where animals are in close contact, often report higher rates of infection.
1.3. Is Ringworm Only a Feline Issue?
No, ringworm is not exclusively a feline issue; it is a zoonotic disease, meaning it can be transmitted between animals and humans. This is an important consideration for pet owners, as ringworm can easily spread through contact with infected animals or contaminated surfaces. Children, elderly individuals, and those with compromised immune systems are particularly susceptible.
2. What Are the Clinical Signs of Ringworm in Cats?
The clearest signs of ringworm include circular areas of hair loss, broken hair, scaly skin, color changes, inflammation, excessive grooming, infected claws, and dandruff.
2.1. Circular Areas of Hair Loss
Yes, ringworm often manifests as circular patches of hair loss, typically starting as small lesions that gradually enlarge. These patches are not always perfectly round, but the distinct shape is a key indicator.
2.2. Broken and Stubbly Hair
Ringworm can lead to hair shafts becoming brittle and breaking off near the skin’s surface, resulting in a stubbly appearance. The American Animal Hospital Association (AAHA) notes that this breakage is due to the fungal infection weakening the hair structure.
2.3. Scaling or Crusty Skin
Scaling or crusty skin is common in ringworm, caused by inflammation and the accumulation of dead skin cells. These areas can be itchy and uncomfortable for the cat, leading to further irritation through scratching.
2.4. Alterations in Hair or Skin Color
Ringworm can sometimes cause changes in the color of the hair or skin in the affected areas. This may manifest as a darkening or lightening of the skin, or a change in hair pigmentation.
2.5. Inflamed Areas of Skin
Inflammation is a typical response to ringworm, leading to redness, swelling, and warmth in the affected areas. The inflammation is the body’s immune system reacting to the fungal infection.
